Quantum Resistance: How New Cryptos Are Preparing For The Future Of Computing
Quantum computing is still in the early stages of development, but experts continue to highlight its potential dangers to the digital landscape. Among these dangers are the ability to break the encryption algorithms that currently protect cryptocurrencies. However, cryptographers are hard at work creating new algorithms that are designed to be resistant to this new threat. This article takes a closer look at quantum resistance and what it means for the future of cryptocurrencies.
What is Quantum Resistance?
Quantum computing takes advantage of the strange properties of quantum mechanics to perform calculations that are impossible for classical computers. Quantum resistance is the ability to withstand attacks from quantum computers. Quantum-resistant algorithms are designed to protect data and systems from being compromised by quantum computers.
Why is Quantum Resistance Important for Cryptocurrencies?
Most cryptocurrencies rely on elliptic curve cryptography (ECC) and RSA encryption, which are both thought to be vulnerable to attack by quantum computers in the future. Since many quantum-resistant encryption schemes already exist, it should be possible to swap the vulnerable crypto schemes for safer versions and avoid a quantum apocalypse.
How Are New Cryptos Preparing for Quantum Resistance?
Several new cryptos are already implementing quantum-resistant algorithms to protect their networks. For example, IOTA, a crypto-currency designed for the Internet of Things (IoT) devices, uses a hash function known as Winternitz one-time signature that is considered to be quantum-resistant. Another example is QRL, a quantum-resistant cryptocurrency that uses a lattice-based signature scheme.
The Future of Quantum Resistance
Post-quantum cryptography has been maturing steadily over the past few years and is now reaching a level of maturity where its deployment can be seriously contemplated. As quantum computers become more powerful, quantum resistance will become increasingly important for cryptocurrencies. Governments, businesses, and individuals will need to begin taking quantum resistance into account or prepare to face the consequences.## Quantum Resistance: How New Cryptos Are Preparing For The Future Of Computing
